[Qemu-devel] [PATCH 1/2] qom-test: Run for all available machines

[armbru@redhat.com]

From: Markus Armbruster <armbru@redhat.com>

Get available machines via QMP instead of hardcoding a list that's
perpetually out of date.

A few machines don't work out of the box:

* Several ppcemb machines can't initialize their CPU.

* Xen machines can work only when running under the Xen hypervisor.

Blacklist them.
